ERWEKA CWS
The ERWEKA CWS acts as the base of all
ERWEKA Check Weighing Systems.
Up to 50 samples can be loaded. The unit will
automatically individualise the samples and
transport them to the balance boat. The weight
is determined by a Sartorius CPA 64 balance.
When the weight is stable, the sam-ple will be
transported into a container.
The unit is operated by an alpha-numeric touch-
sensitive keypad and a full-graphic backlit LC
display. Results can be displayed, hard copied
via the parallel printer port or be transferred to a
computer by the standard RS 232 serial inter-
face.
 Weight measurement boat to eliminate the
problems caused by dust and debris
 Optional diversion unit according to products
and/or tolerances
 Measuring range 20 mg to 20 g
 Throughput max. 20 samples/min. at accu-
racy +/- 0.5 mg (standard) or optional max.
12 samples/min. at accuracy +/- 0.1 mg
(please specify)
 Product memory for up to 49 products to
store nominal values, 3 tolerances and re-
marks under product name and -number
 Integrated programme menu for calibration
of the unit with documentation print-out
 RS 232 and RS 485 serial interface for ex-
ternal control and storage of results by the
optional ERWEKA CWS software
 Parallel printer interface for documenta-tion
of time, date, results and statistics
 50.0 g weight, class F1 for calibration of the
weight measuring station
100-240V/50 and 60Hz 10-410-0000
